Is Alzheimer's disease an individual-centered disease? Hypotheses from the atomic levels up to mathematical models for biological systems.

This article examines the question of whether Alzheimer's disease (AD) is a disease that affects individuals differently. It discusses the biological markers that characterize AD and lead to brain degeneration. The article suggests that different variants of AD may arise from a complex interaction of various factors. It also discusses the presence of other diseases and risk factors in AD, as well as the variability in abnormal proteins and the effectiveness of certain treatments. Overall, the article emphasizes the need for further research to fully understand AD and proposes personalized treatment strategies. [Extracted from the article]
